Technical Field
[0001] This utility model relates to the field of bolt technology, and in particular to a shockproof and anti-loosening self-locking thread fastening assembly. Background Technology
[0002] Bolts are common fasteners primarily used to connect two or more parts with through holes, allowing them to be securely joined together. Bolts can be classified according to different criteria, such as the type of force applied during connection, head shape, and thread length. Based on the type of force applied, they can be divided into ordinary bolts and reamed bolts. Ordinary bolts are mainly used to withstand tensile forces or small shear forces, while reamed bolts are mainly used to withstand larger shear forces. Based on head shape, they can be divided into hexagonal head bolts, round head bolts, square head bolts, countersunk head bolts, etc.
[0003] Fixed bolts can easily fasten objects, but existing bolts often loosen due to vibration and other reasons after a period of use, resulting in poor fastening effect. Therefore, a shockproof and anti-loosening self-locking thread fastening component is proposed. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0019] Reference Figures 1-3 A shockproof and anti-loosening self-locking threaded fastening assembly includes a first plate 1, a second plate 2 connected to one side of the first plate 1, fixing holes on the first plate 1 and the second plate 2, fixing bolts 3 connected in the fixing holes, a nut 4 on one side of the second plate 2, a washer 5 fixedly connected to one side of the nut 4, and a fastening mechanism on the washer 5.
[0020] Furthermore, the fastening mechanism includes a spring 6, a first connecting rod 7, a sliding block 8, a second connecting rod 9, a rectangular block 10, and a locking block 11. One end of the spring 6 is fixedly connected to the first connecting rod 7, one side of the sliding block 8 is fixedly connected to the second connecting rod 9, one end of the second connecting rod 9 is fixedly connected to the rectangular block 10, and one side of the rectangular block 10 is fixedly connected to the locking block 11.
[0021] The first connecting rod 7 has a sliding groove 12, the sliding block 8 is slidably connected to the sliding groove 12, the gasket 5 has a rectangular groove 13 on one side, one end of the spring 6 is fixedly connected to the rectangular groove 13, the first connecting rod 7 is slidably connected to the rectangular groove 13, the fixing bolt 3 has threaded parts 14 spaced apart, and the locking block 11 is located between different threaded parts 14.
[0022] In this process, the first plate 1 and the second plate 2 are combined together, and then the fixing bolt 3 is placed into the fixing block. The nut 4 is tightened so that one side of the washer 5 is in contact with one side of the second plate 2. Then, by pulling the rectangular block 10, the second connecting rod 9 is driven to slide out of the sliding groove 12 until one side of the sliding block 8 abuts against one end of the sliding groove 12. Under the elastic action of the spring 6, the first connecting rod 7 abuts against one end of the rectangular groove 13. At this time, the locking block 11 on one side of the rectangular block 10 is engaged between the threaded parts 14, thereby preventing the nut 4 from loosening.

[0026] The working principle of this utility model:
[0027] After tightening the nut 4, one side of the washer 5 is brought into contact with one side of the second plate 2. Then, by pulling the rectangular block 10, the second connecting rod 9 is slid out of the sliding groove 12 until one side of the sliding block 8 abuts against one end of the sliding groove 12. Under the elastic action of the spring 6, the first connecting rod 7 abuts against one end of the rectangular groove 13. At this time, the locking block 11 on one side of the rectangular block 10 is engaged between the threaded parts 14, thereby preventing the nut 4 from loosening.
